That nothing in the universe moves faster than light is a fundamental axiom of modern physics. The velocity of light is accepted as "basic constant," is given the symbol c for mathematical notation, is counted as 2.9986X10 10 cm. sec.-1-or roughly...
...They cooked on wood, oil and coal stoves, five types of gas ranges, twelve kinds of electric ranges. Sometimes they cooked until the food was burned dry, to see if the glass would stand the continued heat. Eventually they found a glass of which each centimetre expanded only .00000385 cm. per degree of temperature raised, and which continued to hold its heat-resisting properties even through many reheatings...
Frankly, we liked the speech primarily because it was chucked full of fight and vigor. Mr. Roosevelt socked it to 'cm in the language we like to hear. We hasten to add that we have never been in sympathy with all of the President's program.

Other radio engineers read his statement with wonder and respect, awaited details...
...extremely viscous oil coal pulverized as small as 1/10,000 of a mm. would sink with less speed. Also surface energies on the particles would tend to keep the mixture more stable. With coal ground so fine that it would pass through a sieve of 80 meshes to the cm. the sinking would be at a rate of a few centimetres...
